While my print begins fine, mid way it stops and retreats to the Y axis right side of my heat plate.
It has print the same part without any issues before.
I don't know if this is a program setting or printer. Any help would be highly appreciated.

First thoughts are that the printer has suddenly run out of commands to follow.

If you print to file then print from the gcode, have you tried loading the gcode file into S3D to preview it? Doing so will test whether it has written correctly....and test the media you've written the file to.

If you print direct from S3D via USB, what you are describing may be an issue with the USB connection going to sleep. Search the forum for the many threads on the subject.
